"Lazy" GtkToggleButtons

[Stefan Weber lawo de]

I frequently have the need for GtkToggleButtons that emit a 
"toggled"-signal but do not switch state. The signal handler then should 
send a toggle request to a server via network. After receiving a 
confirmation from the server, I wish to toggle the button from code. I 
have not found a way to do so yet. Activating/Deactivating the button in 
the toggled-signal-handler leads to endless recursion. Has anybody else 
found a way accomplish that?
